2 Claims.

the window openings thereof.

The invention also has for its object heat insulating the inner sash'ofthe double sash and the adapter from the transfer of heat through thewindow frame or portion of the car body around the window opening andthrough the sash and the adapter frame to the interior surface of thesash or the car body or the adapter to avoid condensationof moisture onthe inner sash, which runs down and forms pools on the window sills.

Other objects will appear throughout the specification.

The invention consists in the novel features and in the combinations andconstructions hereinafter set forth and claimed.

In describing'this invention, reference is had to the accompanyingdrawing in which like characters designate corresponding parts in allthe VIEWS.

Figure 1 is a fragmentary elevation of a window unit embodying thisinvention.

Figure 2 is an enlarged section on line 2-2, Figure l, the contiguousportion of the car body around the window opening being also shown.

Figure 3 is a view similar to Figure 2 illustrating the adapter foranother construction of car body or different construction of car bodyfrom that shown in Figure 2.

Figure 4. is a view similar to'Figures 2 and 3 illustrating amodification of the adapter shown in Figure 3.

The construction of car bodies or window openings of various makes ofvehicles, as for instance.

Pullman cars, Greyhound buses, etc., differ, and

heretofore the manufacturer and supplier of sash equipment has beenobliged to make the sash to conform to the differences in the car bodyconstructions around the window opening.

This invention comprises means by which the manufacturers standardizedsash can be. applied to the window openings of different makes of carbodies, and therefore the invention comprises a window construction unitincluding a sash and an adapter frame, in which the sash is mounted, thesash and the adapter frame being mountable ill the window opening withthe sash secured at its edge in the adapter frame as a unit therewith,so that the manufacturer and supplier'can supply one type of sash forthe different car bodies together with the adapter frame for theparticular car body in which the installation is to be made. As railwaycars and buses, etc. are usually air-conditioned, the sash are doubleand stationary.

I and 2 designate respectively the outer and inner sash, these beingformedhollow and of metal. 3 designates the adapter frame, and 4 (Figure2) designates generally one type of car bod construction around thewindow opening;- 28 (Figures 3 and 4) another type of car body.

In the form shown in Figure 2, the car body is formed on the outer sidewith a metal sheet, plate or flange 5 opposed to the outer face of thesash I and a backing and weather strip 6 is interposed between theflange '5 and the confronting face of the sash I, this strip '6 beingusually of rubber. The stripis so constructed as to be flexible ratherthan. compressible. It is rendered flexible by reason of the inclinedridges or barbs I in the base portion thereof which flex when the sash Iis pressed against it and also by a flexible lip 8. The construction ofthis strip 6 .per se forms no part of this invention, but constitutesthe subject matter of another application.

One of the sash I, 2, preferably the outer sash I, is secured to theadapter 3 and the inner sash 2 is demountable or openable, it being hereshown as hinged at 9 to the outer sash I. It is secured to the outersash I by quickly operable securing means designated generally I!)carried by the sash 2 and having an arm or button II operable by apartial rotary movement into and out of interlocking engagement with thesash I. .These buttons are operable by means of screws Ill) exposed onthe inner face of the sash 2. The securing means Iii constitutes a unitreadily applied to the sash 2 and secured thereto, as by screws I2.

The glass panes I3 and IA of the sash are seated in suitable resilientlinings I5 in channels in the sash I, 2 and the glass panes are alsoheld in position by removable glazing strips 56, one for each sash I, 2.The glazing strips are located between the glass panes and compressagainst each other upon interlocking of the arms or buttons II with thesash I. They tightly seal the space between the glass panes againstinterchange of air between said space and the atmos phere inside andoutside of the car body. The glazing strips are usually of rubber andare kept compressed against each other and the glass by their ownresiliency under compression, and by spring follow-up means embodied inthe securing parts I 0.

The adapter frame 3 is angular in cross-section, and one flange I'ithereof, in the form shown in Figure 1, laps the inner side of the carbody opposite to that on which the flange 1 is located. and the otherflange 18 extends transversely of the sash I, 2 across the edge thereofand circumferentially around the sash. One of the sash, as the outersash, is secured at its edge to the flange i8 in any suitable manner, asby screws 19 extending edgewise into the sash I. The adapter 3 issecured to the car body around the window cpening by fastening means, asscrews 26, extending through the flange ll of the adapter frame and intoany convenient part, as 2i, of the car body.

A spacer or shim blocks 22 may be located between the car body 4 and theflange I8 of the adapter frame. 23 designates a heat insulating stripbetween the flange I8 of the adapter frame and the edge of the sash I,and 24 a suitable cover strip for the space between the sash I, 2 toprovide a dead air space between the sash.

The weather strip 6 also acts as a heat insulator as do the glazingstrips 16 to prevent the transfer of heat from the outside to the insideof the car body through the metal adapter frame and sash, and thuscondensation of moisture on the inner side of the metal sash 2 and therunning down of such moisture on the sill S is prevented.

In Figure 2, the adapter frame 3 is applied to the car body from theinner side of the car body. In Figures 3 and 4, it is applied to the carbody from th outer side thereof.

In Figures 3 and 4, 3i) designates the adapter frame, whichis secured tothe car body 40 by the screws 20 suitable insulating strip 23 beinginterposed between the car body and the adapter frame 30. T 22designates spacers or shims between the adapter frame 30 and the outersash I.

In the form shown inFigure 3, the adapter frame is located between afinishing sheet 25 and the car body, this sheet lapping the sash I withitsupper edge located in a groove at 26 formed in the sealing strip lfor the glass pane l3. A suitable heat insulating strip 2'! isinterposed between the sheet and the face of the sash I.

In Figure 4, a construction similar to that shown in Figure 3 is shownfor a construction in which the body is not provided with a finishingsheet 25. In this form of the invention, the adapter frame is formedwith a head or flange 28 covering the joint between the sash I and theadapter frame 30.

The sash l, 2 are the same in any of the installations, but thesestandardized sash are adaptable to the various types of window openingsor to the portions of the car body around the window opening by means ofthe adapter frame 3 or 30, so that by reason of this unit consisting ofthe sash and the adapter frame, a standardized sash may be economicallyapplied to the various car body constructions; and the sash insulatedfrom the adapter frame, the insulation not only preventing theconduction of heat or cold but also absorbing some of the vibration orweave of the car body structure and relieving the sash unit of theweaving effect.

What we claim is:

1. The combination with a car body formed with a window opening; of awindow construction unit comprising opposing sash, an adapter framemountable in the window opening from one side of the body, the car bodyon the opposite side having a flange opposed to one of the sash, andmeans for securing that sash at its edge to the adapter frame, the othersash being secured to the sash which is secured to the adapter frame.

2. The combination with a car body formed with a window opening; of awindow construction unit comprising opposing sash, an adapter framemountable in the window opening from one side of the body, the car bodyon the opposite side having a flange opposed to one of the sash, meansfor securing that sash at its edge to the adapter frame, the other sashbeing secured to the sash which is secured to the adapter frame, theadapter frame having an outwardly extending flange lapping the bodyaround the window opening, and means for securing the last flange to thebody.
